Warning, you're about to feel old. Why? Because Buffy the Vampire Slayer premiered 19 years ago on The WB. The first episode of the supernatural series starring Sarah Michelle Gellar debuted as a midseason replacement on March 10, 1997. Yep, we're just one year shy of the 20th anniversary mark.

"19 years ago tonight, I got to introduce you to #buffyannesummers (and #mrpointy too) thank you for taking the incredible journey with me and continuing still. I am and forever will be #grateful," she captioned the photo below.

Buffy went on to run seven seasons (five on The WB, two on UPN) and spawned a spinoff, Angel. The adventures of the character are still going on in a Joss Whedon-sanctioned comic book series.

Despite reboots and revivals being all the rage, don't expect a Buffy reunion with the show's cast. Gellar has joked about needing a walker of stakes to play the hero again. In an interview, Gellar opened up about the "curse" of BtVS.

"There is only one curse and it's not what people expect," Gellar told Confidential, an Australian publication. "The one curse is, as an actor, you get very spoiled because you think all female characters are going to be that exciting, that interesting, that flawed—and that's really not the case in Hollywood. That's the drawback—you have a standard of what to expect in the characters you play."
